ARTIFICIAL-SILK-SPINNING MACHINE.

Application filed December 30, 1920. Serial No. 434,000.

To all whom it may concern:

Be it known that I, GEORGE Joan, re-.

cently a subject of the former Austro-Hun- My invention relates to mechanism forforming filamental threads known as artificial silk filaments and has for its object the formation of a yarn made up of a number of such filaments, which yarn will be as nearly .as possible uniform in weight and thickness. Another object which I have in View is in connection with the use of intermittently acting pumps which alternately force the collodion or other material through the spinnerets to maintain a practical continuous flow of material through the spinnerets and I have also in view the combination with'a spinneret header of two alternately acting pumps. each having a holding capacity for material tobe formed into filaments sufiicient to produce a quantity of yarn formed of filamental threads suiticient to fill a bobbin or spool.

The nature of the invention which I have made -to carry out the above mentioned primary objects and to provide full mechanism for doing so will be best understood in'connection with the drawings which illustrate a machine embodying my invention and improvements in what I believe to be their best and most practical form and in which Figure 1 is a plan view of the machine 9 taken as on the section line 1-1 of Fig. 2.

A, A, etc. indicate the vertical members of the machine frame; A A, transversely extending portions of the frame'at the bottom thereof; A A transversely-extending portions of the frame at the top thereof; A A

longitudinally extending beams supported, as shown, on the frame portions A. A, A, are longitudinally extending rods supported on the frame portions A B, B, etc. are a series of pump cylinders supported on the beams A and wormed in pairs in alignment with each other; each of these cylinders, as shown, see Figs. 11 and 12, is provided with a gland B in its opposite end. C, C', indicate plungers working in the opposite cylinders B and B and preferably, as shown, formed in theends of a continuous rod, the central portion of which is screw threaded as indicated at C D is a nut screwing on the threaded portion C of the flange rod and 8 is a plan view ofthe upper part having a worm Wheel D formed on or secured to its periphery. The nut and worm wheel are held in fixed position by arms D D supported on the frame of the maarm H. the lower end of a vertical shaft H supported on the machine and having an it with chine. E is a shaft extending longitudinally of the machine and suitably supported on pedestals such as A such shaft having formed on or secured to it a series of worms E in engagement with the worm wheels D of the nuts D. E is a sliding clutch member longitudinally movable on the shaft E but keyed to the shaft which has to revolve with it. E and E are co-acting clutch members free'to revolve on the shaft E but held in fixed longitudinal.position thereon. E and E are bevel gear wheels secured to the clutch members E and E and both engaged with the bevel gear F secured to the main driving shaft F which has also secured to it a gear wheel F which engages a gear wheel G 011 a shaft G on which shaft is keyed a clutch member Gr free to slide longitudinally on the shaft so as to engage with either the clutch member G or the clutch member G which are freeto rotate on the shaft G and each of which is provided with a bevel gear wheel indicated at G G. These bevel gears are in engagement with the horizontal bevel gear indicated at H from which extends a finger or The bevel gear H is supported (in suitably elongated gear wheel H secured to its upper portion. This gear wheel in turn is in engagement with the rack I secured to a longitudinally extending bar I.which at one end engages a lever arm I secured to a shaft I to which shaft is also secured a forked lever I in engagement with the clutch member E. J is a forked lever in engagement with the clutch member E and actuated through a shaft J and an arm J best shown in F 1g. 10, and which is pref erably provided with spring arms J 3 and J extending downward from its upper end. These spring arms, see Figs. 4 and 5, extend into positions in which they lie in the path of the finger or arm H extendin out from the periphery of the bevel wheel K and K, best shown in Figs. 5 and 6, are fingers or arms extending out from a rod K which rod is secured at one end to an arm K secured, as shown, to the plun er shaft of the plunger C, C, as by a ring {4 and held in position by a guide 'rod K K indicates a guide secured, as shown, to the cylinder B which supports the rod I 2 but permits it to slide thereon.

L is a supply conduit for the material to be converted into artificial silk filaments. This material is supplied to a conduit maintained under as nearly as possible constant pressure therein by means of pumps not shown, the pressure under which the material is maintained being as nearly as' possible equal to that which is necessary to force the desired speed through the spinnerets attached to the various spinneret headers connected with the conduit in the manner to be hereafter described. L, L, etc. are a series of pipes leading from the supply conduit, L, one being provided for each pair of connected pump cylinders. Each pipe L leads to a four-way valve M from which leads a delivery pipe L Also leadin from the four-way valve M are pipes 3 and L connecting respectively with the opposite cylinders B and B with each pair of pump cylinders.

The construction of the four-way valve M is best shown in Fig. 9 which is provided with four parts m, m, m and m connected respectively with pipes L, L", L and L and to the cylindrical valve seat indicated at m in which works a cylindrical valve N having formed in it ports N and N 2 supported by the partition N which partition 1 is of such dimensions that, as is indicated by dotted lines in Fig. 9, it will not close the ports m and m when turned into alignment with these ports and so that in moving the valve from the position shown in Fig. 9, for instance, to a position in which the pipe connections are reversed a direct communication will be formed from the ports m to the port 111*.

O, 0, etc. are lever arms secured to the valves N at one end and connected at their opposite end to the reciprocating rod or plate It.

P indicates a. filter which is connected with each of the pipes L and from which a pipe P or 1? leads to a spinneret header Q- and Q. These spinneret headers are supported on the rods A, A, as shown, and are disposed in groups on opposite sides of the machine, each spinneret header having secured to and in connection therewith a group of spinnerets indicated at Q the filaments from the spinnerets of each-header being guided and covered by fingers and grooves indicated at R, R and R so that they form a yarn which is run on a bobbin or spool'indicated at B, Fig. 7.

The operation of the machine is as follows: Assuming the driving shaft F to be in constant operation it is obvious that this motion is transmitted throughthe gears F 2 and G to the shaft G and to the clutch member G: which slides on but rotates with this shaft. The bevel gear F secured to the shaft F is also in constant rotation and transmits rotation in opposite directions to the bevel gears E and E and the clutch members E and E secured thereto and obviously the. shaft E would berotated in opi posite directions depending on whether the clutch member E is engaged with the clutch member E or the clutch member E The rotation of the shaft E impartsthrough the worms E rotative movement to the worm wheels D and the nuts D which, acting on the screw threaded intermediate portion 25 terial shall-be forced through the spinnerets The capacity of the cylinders B and B is preferably such that each will contain, when the plunger is retracted to its full extent, an amount of material suflicient when manu factured into yarn, to fill one bobbin or spool. This is quite important as: it insures or may be made. to insure that the filaments into which the cylinder charge is manufactured and each charge to be manufactured into a yarn andwound upon a bobbin shall in all cases be made up of an equal weight of material, that is, that the yarn shall be'of uniform weight and it also provides or may be made to provide for the shifting of the yarn from a full bobbin to an empty bobbm during the interval between the reciprocating strokes of the pump, that is during the period when aninequality in the weight of the yarn is most apt to occur.

The material to be converted into filaments -is maintained in the conduit 'L under pressure as nearly as possible equal to the pressure under which it is intended that the maand the valves N being, for instance, in the position shown in full lines in Fig..9, the

' material flows through the conduit L through the pipes L into the port m, thence through the valve port N to the port m into the pipe L and from said pipe into the cylinders B in which the plungers C are moving downward at the same time the plunger C moving inward in the cylinders .B forces the material through" the pipes L into the ports m and through the ports N of the valve into the ports m and thence through the pipes L through the filtersP intothe pipes P and P and into the headers Q and Q, from which the material issues through the spinnerets Q each header having connected to it a group of spinnerets equal in number to the number of filaments which it equal to the pressure maintained in the headers but little power will be required to move the plungers C, C, the pressure transmitted through the conduit to the receiving plunger C, for instance, being nearly sufiicient.

to force the plunger C into the cylinder B with 'suflicient power to maintain the necessarv pressure in the connected header.

- At. the and of each stroke of'the connected pistons it is, of course, necessary to reverse the valves N and it is animportant feature of my invention that I provide a valve which during its motion to reverse the flow of the I filament making material operating to pro- H will flow directly to the headers and maintain an approximately constant feed which will insure not only against a stoppage of flow but a nearly continuous flow, so'that even during this interval there will be little or no variation in the weight of the yarn.

To-return now to the driving mechanism shown in the drawing, the clutch E is in engagement with the clutch member E so that the shaft E is being rotated by the said clutch member E, the clutch member G keyed to theshaft member G is out of engagement with the clutchmembers G and G and consequently thebevelgearsG and G and the bevel gear H are stationary; The .lever J lies in the position indicated in Figs. 4 and 6 and, as indicated in Fig. 6, the

0 outward the collar K travelling with the plunger rod moves the arm K? and the rod K and toward the end of this movement on the finger K comes in contact with the lever J 2 moving it gradually until; it passes over the center when the weight at the head of the lever causes it to fall and through the rock shaft J and fork J moves the clutch member'H into engagement with the clutch member G which seats the gear G in rotation and causes the gear H to rotate also its attached shaft H? and the gear H which, acting on the rack I, performs two functions. first, through the lever I rack shaft I and fork I which first disengages the clutch member E from the clutch member E and at the end of this movement engages the clutch member E with, the clutch member E thus'reversing the direction and rotation of'the shaft E and through its geared connections reversing the direction and movement of the plungers in the cylinders. ,Secondfthe movement ofthe rod I through the levers 0 reverse the valves N and through these valves, of course, reverse the connections of the cylinders B and B with the supply conduit'and the headers,

' While these movements of the lever arm I and of the levers Ofare taking place the rotation of the gear wheel H carries the finger H through a circular position until it comes in contact with one of the spring arms J a and J on the lever J 4 and the yielding pressure thus applied turns the lever J in a direction to move the clutch member H out of engagement with the clutch member G and when these clutch members have been disengaged the resilience of the spring through which the lever J 2 has been moved is such as to move it a short distance'farther so as to insure that the clutch members will be sufiiciently apart to. avoid the risk of a reengageme-nt. As soon as the clutch members are disengaged the rotation of the gear wheel H and its connected mechanism ceases and these parts remain stationary until at the end of the reversed movement of the plungers the finger K comes in contact with the lever J and moves it over the center so that it will engage the clutch member G with the clutch member G causing the rotation ofthegear wheel H in the opposite direction to that in which it revolved previously and through the mechanism described reversing the connection with the clutch member E and reversing the operative posi tion of the valves N.

\Vhi-le, as required by law, I have illustrated and described my invention in what I believe to be its best and most efiicient embodiment I wish it to be clearly understood that my invention may be embodied in many modifications of the specific mechanism illustrated and that I do not wish to be under-- stood as limiting my claims on any of the specifically illustrated and described devices except where such devices are specifically called for in the claims.
